How to use MULTISIM to generate PWM waves with different duty cycles? [Copy link]

How to use MULTISIM to generate PWM waves with different duty cycles? How to build the circuit specifically? And how to measure the effective value of the generated PWM wave in this software? Or is there any way to calculate and measure the effective value of the generated PWM wave?

MULTISIM is a circuit simulation software. This software simulates PWM wave through duty cycle through specific circuit.

For example, a simple PWM circuit, ne555 to realize PWM wave, can be simulated by this software, duty cycle adjustment

For example

555 uses RC to adjust the duty cycle, right?

The following circuit uses Proteus to simulate the PWM wave of 555

You can build a circuit simulation in multisim

I learned to use Proteus for simulation when I was in school. I learned about multisim later in my work, but I have never used it.
